                         DYNAMEX ANNOUNCES FIRST QUARTER
                            FISCAL YEAR 2004 RESULTS

FIRST QUARTER HIGHLIGHTS:

o        SALES INCREASE 13.5% TO $70 MILLION.

o        NET INCOME INCREASES 14.3% TO $2.2 MILLION OR $0.20 PER FULLY DILUTED
         SHARE.

o        EXPANDS LOGISTICS CENTER IN CHICAGO.

o        BEGINS SERVICE IN NEW MARKETS.

o        MANAGEMENT REAFFIRMS FY 2004 OUTLOOK.

DECEMBER 3, 2003 -- DALLAS, TEXAS -- Dynamex Inc. (Amex: DDN), a leading
provider of same-day delivery and logistics services in the United States and
Canada, today announced net income of $2.2 million or $0.20 diluted earnings per
share for the first quarter of FY 2004, an increase of 14.3% compared to the
same period last year.

Sales increased 13.5% to $70 million in the FY 2004 first quarter compared to
the prior year, the second consecutive quarterly sales record for the Company.
Sales were positively impacted by a 15.9% increase in the average exchange rate
between the Canadian dollar and the U.S. dollar compared to the prior year.
Excluding the effect of the exchange rate, sales increased 8.2% this year
compared to last year. Earnings before interest, taxes, depreciation and
amortization ("EBITDA") were $4.2 million compared to $4.1 million in the same
quarter last year (see Reconciliation of Non-GAAP Financial Measures on page 8
of this release).

Selling, general and administrative ("SG&A") expenses increased 8.0% to $15.5
million in the FY 2004 first quarter compared to the prior year period. As a
percentage of sales, SG&A expenses were 22.1% in FY 2004 compared to 23.2% in
the prior year. Approximately 50% of the increase is due to the change in the
exchange rate between the Canadian dollar and the U.S. dollar. The remaining
increase in the current year quarter is primarily attributable to the relocation
and expansion of our Chicago facility, the cost of additional personnel to
manage and service significant new business startups in a number of U.S.
locations, an increase in compensation expense related to a larger sales force
and higher sales commissions from new

business, the expensing of stock options beginning this fiscal year, higher
communication and software maintenance fees and increased state unemployment
taxes and health insurance premiums.

Other income for the FY 2004 first quarter was $88,000 compared to $14,000 in
the prior year period. The increase is primarily attributable to foreign
currency transaction gains realized on the payment of Canadian dollar
denominated inter-company royalties and interest to the U.S. parent in the
current year quarter.

FIRST QUARTER HIGHLIGHTS

"We are very pleased with the results for the quarter," said Dynamex Chairman
and CEO, Rick McClelland. "Our momentum in the same-day transportation industry
continues to increase as evidenced by our 13.5% increase in sales and 14.3%
increase in net income. We attribute this success to our outstanding workforce,
our investment in the largest sales organization in our industry, our focus on
regional and national customers and a business model that is geared to perform
well in just about any economic environment because of our non-asset based,
variable cost structure plus a service menu that allows Dynamex to scale
operations to meet our customers' requirements.

"Our position in the same-day transportation industry is unmatched and
strengthening," McClelland added. "No other single provider can match our scale,
services, experience and coverage throughout the United States and Canada. This
major differentiation between Dynamex and other providers is becoming
increasingly evident to prospective customers as we continue to win new
business. For example, during the past 120 days, Dynamex established just under
200 additional routes in 23 markets for certain National Accounts. Some of these
installations were in new markets for Dynamex including Nevada and Michigan as
well as additional locations in California.

"In order to meet this demand, we had to deploy start up teams in multiple
markets simultaneously and at the same time add to our operational capabilities
in order to meet new ongoing requirements. Although extremely challenging, the
start-ups were successful both in terms of operational execution and economic
results. This success was especially important as the on-demand market has
remained generally flat," McClelland continued. "On the cost side of the house,
our industry, like many others, continues to experience rising costs in a number
of areas including insurance and health care. We will continue to vigorously
pursue growth but also opportunities to improve our cost structure.

"We are continuing to reposition Dynamex in order to decrease our reliance on
the sluggish on-demand market by responding to various, significant distribution
opportunities," said McClelland "Keep in mind that just 36 months ago our
business mix was 60% on-demand services whereas today it represents less than
44% of total sales. This is why the opening of our expanded Chicago Logistics
Center is so important. Sales from operations in the Chicago area represent
slightly less than 10% of our total sales in the U.S. and the opportunities on a
go-forward basis are tremendous. In this facility we have over 50,000 square
feet of warehouse space that is utilized for emergency parts banking plus
deconsolidation and cross-docking related to our local

and regional same-day distribution service offerings. This facility also houses
our on-demand dispatch operations, plus our local sales and general
administrative functions. The Chicago area is a critically important market area
for Dynamex and therefore this expansion of our capabilities is an extremely
exciting event.

"A transition like ours is challenging but two things are reasonably clear,"
added McClelland. "First, we are capitalizing on new business opportunities.
Second, our people are bottom line oriented as evidenced by our strong results
during a prolonged 'down' market. The net result is strong penetration of our
target markets and further improvement of our market position, achieved without
negatively impacting earnings. We remain highly focused on enhancing the
mid-to-long term prospects for Dynamex.

"We continue to forecast fiscal year 2004 net income of between $0.75 and $0.85
fully diluted earnings per share which would put us on track for a
year-over-year earnings improvement of from 14% to 29%." McClelland concluded.
"Through the balance of the fiscal year, we will continue to focus on increasing
sales, improving net income and strengthening our capital structure by reducing
debt. We believe we are well positioned to achieve these goals and further
improve shareholder value."

DEBT REDUCTION

Long-term debt (including the current portion) was reduced by $0.6 million in
the three months ended October 31, 2003. The Company borrowed $1.0 million under
the bank line-of credit, paid the scheduled quarterly term-loan installment of
$1.375 million and retired the remaining $248,000 of seller financing notes
during the quarter. An additional bi-weekly payroll ($2.1 million), capital
expenditures ($0.9 million) and increases in working capital ($3.4 million),
less $1.5 million of cash payments by Canada to the U.S. for inter-company
interest, royalties and a cash dividend are the principal reasons for the net
increase in the bank line-of-credit.

MARGINS

The gross margin was 28.0% of sales in the current year quarter, down 6.0%
compared to 29.8% in the prior year quarter due to the continuing shift in
business mix from on-demand to other services and higher insurance and claims
expense and down 2.4% compared to 28.7% in the fourth quarter of FY 2003.
EBITDA, as a percentage of sales, was 6.1%, down from 6.6% in the prior year
quarter due, in large part, to higher insurance and claims expense ($360,000),
the Chicago facility relocation ($100,000), higher medical and dental premiums
and state unemployment taxes ($150,000) and stock option expense ($50,000).

DEPRECIATION AND AMORTIZATION

Depreciation and amortization ("D&A") in the first quarter 2004 decreased to
$512,000 from $580,000 in the first quarter of 2003. As a percent of sales, D&A
was 0.7% compared to 0.9% in the prior year. The reduction in D&A in the current
year is primarily attributable to lower capital expenditures in recent years.

INTEREST EXPENSE

Interest expense for the three months ended October 31, 2003 was $332,000, 46%
below the prior year period. This decrease is primarily attributable to lower
outstanding debt and a lower interest rate that includes a reduction of 100
basis points in the margin on outstanding loans in the current year quarter
versus the prior year quarter due to the Company's improved EBITDA ratio.

OUTLOOK

The following outlook for FY 2004 is provided in connection with Regulation FD
and to ensure that all investors continue to have equal access to information.
The following outlook contains forward-looking statements that involve
assumptions regarding Company operations and future prospects. Caution should be
taken that the actual results could differ materially from those stated or
implied in this and other Company communications.

Management remains focused on the long-term growth and profitability of the
Company. The outlook presented herein is for the full fiscal year and does not
address expected results of operations by quarter.

The Company expects year-over-year sales growth, including the foreign exchange
impact, of between 12% and 16% for fiscal year 2004. The Company expects the
Canadian exchange rate to average $0.74 for the remainder of this fiscal year.

Dynamex expects FY 2004 gross margins to decline versus the prior year as the
percentage of scheduled and distribution and outsourcing sales increases
compared to on-demand sales. The EBITDA margin is expected to range between
5.75% and 6.25% of sales for the full fiscal year. The Company expects SG&A
expenses to increase in absolute dollars but decline as a percentage of sales.
Incremental costs to comply with Sarbanes-Oxley are expected to range between
$300,000 and $400,000 for the remainder of this fiscal year. Depreciation and
amortization is not expected to change significantly in FY 2004 from current
levels. Interest expense is expected to decline in FY 2004 due to a lower level
of debt, relatively stable interest rates, lower amortization of financing costs
and a reduction in the margins charged by the bank group. Capital expenditures
are now expected to be in the $2.0 million range.

The Company expects the effective income tax rate for FY 2004 to be
approximately 30% as available net operating loss carryforwards will offset
taxable income in the U.S. This outlook does not contemplate recognizing the
benefit of available, but unused U.S. tax benefits above those amounts utilized
in the current year to offset taxable income.

The Company is reaffirming its expectation that net income for FY 2004 will
range from $0.75 to $0.85 per fully diluted share. Also, the Company expects to
reduce long-term debt by approximately $7.0 million in FY 2004.
